Let's say it one time with feeling--Now, this is a situation.

Jersey Shore's resident ab man Mike "The Situation" Sorrentino filed a breach of contract lawsuit against Devotion Vodka, E! News confirms, claiming the company cheated the reality star out of millions after Sitch held up his end of the bargain.

In 2010, Mike agreed to endorse the protein-infused vodka (sounds super delish, right?). The MTV star claims he did his job and is the reason the company has gained success since then, and wants his payoff.

According to court documents, Sorrentino's camp claims that in 2010, the company was "valued at approximately $4 million; two years later, largely due to Sorrentino's endorsement efforts and the brand recognition he cultivated for Devotion, the company is estimated to be worth between $35 million and $50 million (the exact value is unconfirmed because defendants refuse to provide Sorrentino and MPS with quarterly company statements)."

Sitch received the 8 percent ownership stake in the company, as promised, but Devotion failed to add 2 percent to his ownership share on their one-year anniversary, which was promised in the deal.

Additionally, Mike alleges Devotion failed to provide him with a $400,000 "buy back" option for his shares on their two-year anniversary and failed to supply him with sales reports, and claims the company kept looking for an excuse to cut him out and avoid paying him.

Sorrentino is suing for his entire 10 percent share in the company (an estimated worth of up to $5 million) and other damages.
